I'm into the theme involving (usually forced) surgical mutilation

Like the comic where the girl gets an arm amputated for an art project or the one where the girl gets all her limbs removed to live in a tube or something, I can't remember the details...

Where it's considered """normal""", like a rite of passage in that society or some fucked up community project or something

Does anyone know where I can find more of that?

Bonus points if it's done proper with no mindless flesh ripping or anything, as if the procedure was completely normal
